Answer:
10 rad 3 / 2
Step-by-step explanation:
x = missing angle of the full traingle
180 - (90 + 60) = x
180 - 150 = x
30 = x
10 rad 3 / 2 = x
this is just my understanding of the problem- im sorry if im incorrect
You answer is B because supplementary is 180°
Equation 1 :
| 5x - 6 | = -41.....no solution because an absolute vlue cannot equal a negative number
equation 2 :
| 7x + 13 | = 27...2 solutions
C. equation 2 has more solutions then equation 1.
Answer:
a = 9
Step-by-step explanation:
2(a + 7) = 5a - 13
We want to bring a to one side, I will choose to bring it to the right
First, expand the bracket by multiplying 2 with a + 7
2a + 14 = 5a - 13
Bring the -13 to the left by adding 13 to both sides
2a + 14 + 13 = 5a - 13 + 13
Simplify
2a + 27 = 5a
Bring the 2a to the right by subtracting 2a from both sides
2a - 2a + 27 = 5a - 2a
Simplify
27 = 5a - 2a
27 = 3a
Bring the 3 to the left by dividing both sides by 3
27÷3 = a
Simplify
a = 9
